InvalidArgumentException on save CKAN Registry Page with wrong "Successful" message on client side.

[sabina-talipova]

Description

When user saves CKAN Registry Page he gets "Saved 'New CKAN Registry Page' successfully." message, but highlighted as error (has ".toast--error" class). It happens since Back end returns Exception on "Save" request with the following message :

[Emergency] Uncaught InvalidArgumentException: Invalid sort column "CKANResourceField"."Position"

After that page is broken and user cannot open it again.

Steps to reproduce issue

• I go to "/admin/pages"
• I press the "Add new" button
• I select the "CKAN Registry Page" radio button
• I fill in "Page name" with "My CKAN Registry Page"
• I press the "Save" button
• I should see a "Saved" success toast (Right green message)
• I click the "Data" CMS tab
• I fill in "DataResource-uri" with "https://catalogue.data.govt.nz/dataset/directory-of-educational-institutions"
• I wait for 5 seconds
• I should see "Early Childhood Services (ECE) Directory"
• I select "New Zealand Schools" from the ".ckan-resource-locator__resource-select select" field
• I wait for 5 seconds
• I press the "Save" button
• I should see a "Saved" success toast (Exception with Successful message and error style)

AC's

• [ ] Page is saved successfully
• [ ] Toast style matches state.
• [ ] No exceptions are thrown.

Stretch goal

This will probably be fixed as a part of https://github.com/silverstripeltd/product-issues/issues/644 - but I'll leave it open until I'm sure.

I've done a few tests and it looks like was already fixed. No any other issues happened. I close this task as no longer existing.
